principal papers hardware The 4004 demo board only used the 4004 and 4002,
the ROM was simulated with the I1701 EPROM. The multiplexed bus made
it impossible to simulate the read/write functions of the Ram with
logic in the same space as the 4002. It could have been done though. Of course, the benefits of the 1701 EPROM in a development situation could not be outclassed in any form! That is the same organization as that on the diagram from early 1968, a CPU with it's Registers and the RAM (working memory), ROM (program memory) and I/O outside! A Single Chip Computer is like the 8048, where the ROM or EPROM Program memory, RAM working memory, CPU and Registers are on one piece of silicon! That did not occur until 1975.

Achievement
Pickette conceptualized the design for putting a computer on a chip,
1968. He participated in the development of the first Microcomputer. Biography He graduated from San Martin, Ca. Elementary School. Intel hired Pickette, and he joined Ted Hoff's team, working on the Busicom project. The chip Hoff, Stan Mazor, and others designed became the 4004 processor. Pickette introduced the Intel 4004 in Las Vegas, Nev. in 1971.
ChronologyLate in 1962, he decided to begin the study of electronics. He began to reserve technical books through the Santa Clara County Bookmobile. Soon he was reading five to six books per week. 1964 disenchanted him with the library system as a means to study
Technical materials. His design progressed until it became too complex to perform the calculations by hand. The Chemistry Science Professor at Live Oak High School introduced him to two Scientists at Berkeley Radiation Laboratories. He met them, became, an understudy. In addition, they provided him with a version of ECAP in FORTRAN II. They also arranged for him to have access on the Math Department IBM 1620 in the basement of Birge Hall, on the U.C. Berkeley Campus. His design progressed. By 1967, he had evaluated and constructed
the means to capture, store and distribute the material. He used an
Image-Vidicon to read Super-8 film, stored that video on .75"
Tape traversely scanned. When read, the Video Pages would be copied
from the big tape to a circulating tape-loop, which repeated the pages
as necessary for broadcast. He utilized Channel 3 in the VHF band,
and a delay line box at the TV recorded the page and held it on the
screen until the next page arrived. By the late of 1966 his ECAP data set was so enormous that the 1620 crunched on it from 4 a.m. Saturday till 7 p.m. Sunday, his window for utilization of the 1620 was from Midnight Friday till Midnight Sunday. He was not able to receive the printout, which progressed at one line before the Midnight Shutdown. Another friend was attempting to get him some time on an IBM 7094 at the San Jose Plant. This did not pan out. Right in the middle of this project, just before he received that outrageous telephone call from the Lawyer representing that Professor at the University of South Carolina, he read the science fiction novel "I Robot", he decided that humanoid Robots could be made by the end of the current Century or just beyond that. He was also checking different so-called Minicomputers to see which could best match the 1620 or better it's performance. He also had a spending cap of $ 10,000, which had been worked out, between his Father and himself. He decided to evaluate and or purchase one at the Wescon show in San Francisco that spring of 1967. He arrived at the Wescon show, with a paper printout of the calculation core of his ECAP program. He intended to purchase the computer that ran the program if it could. Two of the companies refused to allow him to run his program on their computers. Two allowed him to do it. After running the program on one computer, he decided it was in the right price range and was fast enough. He purchased the DEC PDP-8/S. He studied the PDP-8/S because it required maintenance, and he could not afford the visits of the service guy, who had to travel 50 miles and never arrived before 11 a.m. the next day! He began to study Logic, once because he saw it as the means to control his video presentations and to maintain this computer. By the time he actually went to DEC School in the winter of 1967 he already knew everything about the computer and was writing assembly language programs for it. Received the specification of the newly developed Fairchild 74181 Arithmetic and Logic chip in the mail ,he decided this chip could form the core of a computer with supporting logic. He then set about the design of this computer. He produced a logic block diagram depicting an organization to reduce
a PDP-8/S to chip size with some architectural enhancements. He began
the design just before leaving for Boston, worked on it in Boston
and completed it by mid-January of 1968. By February, he was calling
Fairchild and Hewlett Packard about the concept; one flatly turned
him down, the other never returned the call. His mentor, Mr. A. Rock, of San Francisco, had called and asked him how the approach to Fairchild had gone. After he told him, they gave him the cold-shoulder, he suggested he should apply to IBM for employment. He did, and they refused him on the basis that he was not a College Student. Mr. Rock called again to find out how IBM had gone; when he told
him he was refused he said OK and then hung up. Two weeks later IBM
called and wanted to discuss position and salary for the summer of
1968. If his application to IBM can be found, he listed the computer
on a chip as one of his projects. He pioneered and advocated the first microprocessor Chip & family.
He designed, under contract, the computer controls for the first
low-cost retrofit system for Automatic Ink Mixing and paper alignment
for WEB type Printing Presses. Using the Money from the WEB Printing
contract, WALMOR DATA SYSTEMS was formed. As one of the developing
partners in a two man design team, they produced the first Universal
EPROM& microcomputer Programmer. This programmer was delivered
with multi-protocol He unsuccessfully attempted to purchase Fairchild Semiconductor
Systems, with a bid which was right on the money! With the Solomon
Brothers (Chicago) backing, they approached He conceived of Work-Trak, a bar code driven Work in Progress reporting system. Work-Trak qualified for free advertising in four publications. The Work-Trak Product gained greater than 3000 inquiries from around the world. Only $ 495.00 was spent on advertising, rent of a 4x5 Camera, purchase of film, processing of film, telephone and postage. Purchase orders were accepted for six systems totaling over $ 200,000.00
sales. The product could not be delivered due to several reasons.
The company was shut down and the offices were vacated in August of
1990. I met and married a Russian, Dr. of Mathematics after the Russian
Autovaz Plant sent a Telex inquiry concerning Work-Trak. I met my
wife Anna in the quest to supply the Autovaz with the user's manuals
for the device, in Russian. EDService, Ltd. initially formed to provide Mathematical Education
via the Internet Honors and awards
